The SVS app for controlling the sub has a great interface and easy to navigate. It has fairly detailed settings for optimizing the sound.

You may need to research what each setting does, or you can just play around with the settings to find what sounds best to you. Also, you can restore the app settings back to default at any time, just in case you make too many changes and want to start fresh.

My favorite feature is that with the included remote or the IOS/Android app, you can control the volume of the sub from where you sit. I absolutely love this thing!
